Magnetic, electronic, and structural investigation of the strongly correlated Y\(_{1-x}\)Sm\(_x\)Co\(_5\) system

SmCo\(_5\) and YCo\(_5\) are isostructural compounds both showing large magnetocrystalline anisotropy, where the former originates mainly from the crystal-electric field and magnetic interactions. We investigate the contribution of both interactions by partially substituting Y by Sm in as-cast polycrystalline Y\(_{1-x}\)Sm\(_{x}\)Co\(_5\) (with \(x\)=0, 0.1, 0.2, 0.3, and 0.4) and measuring their structural, magnetic, and electrical properties through X-ray diffraction, magnetization, and electrical transport measurements. Our results suggest an interplay between microstructure strain in as-cast samples and the electronic and magnetic interactions.
